The [ 10 ] annulene given in section 14.7 B is not aromatic . The factor that makes the given 10 π − electron system aromatic is to identified. Concept introduction: Annulenes belong to the class of monocyclic compounds and are represented by the structure containing alternating single and double bonds. For an annulene to be aromatic, the molecule should have ( 4 n + 2 ) π electrons and a planer carbon skeleton.

Question

Definition Definition Rule that estimates whether a given organic planar ring structure will show an aromatic property. A cyclic ring molecule is said to follow Hückel’s rule if the л-electrons count in a molecule is [4n+2], where n stands for a positive numerical value. It is also called the [4n+2] rule. Hückel's rule, sometimes referred to as the aromaticity rule, is one but not the only criteria to judge a molecule for aromaticity.
